# Google Cloud Functions | Sentry for Google Cloud Functions

This guide is for `@sentry/google-cloud-serverless` version `8.0.0` and up.

##### Using Cloud Functions for Firebase?

If you're using [Cloud Functions for Firebase](https://firebase.google.com/docs/functions), see our dedicated [Firebase guide](https://docs.sentry.io/platforms/javascript/guides/firebase.md) for a simpler setup using `@sentry/node`.

## [Prerequisites](https://docs.sentry.io/platforms/javascript/guides/gcp-functions.md#prerequisites)

You need:

* A Sentry [account](https://sentry.io/signup/) and [project](https://docs.sentry.io/product/projects.md)
* Your application up and running

## [Step 1: Install](https://docs.sentry.io/platforms/javascript/guides/gcp-functions.md#step-1-install)

Choose the features you want to configure, and this guide will show you how:

Error Monitoring\[ ]Tracing\[ ]Profiling\[ ]Logs

Want to learn more about these features?

* [**Issues**](https://docs.sentry.io/product/issues.md) (always enabled)
  <!-- -->
  :
  <!-- -->
  Sentry's core error monitoring product that automatically reports errors, uncaught exceptions, and unhandled rejections. If you have something that looks like an exception, Sentry can capture it.
* [**Tracing**](https://docs.sentry.io/product/tracing.md):
  <!-- -->
  Track software performance while seeing the impact of errors across multiple systems. For example, distributed tracing allows you to follow a request from the frontend to the backend and back.
* [**Profiling**](https://docs.sentry.io/product/explore/profiling.md):
  <!-- -->
  Gain deeper insight than traditional tracing without custom instrumentation, letting you discover slow-to-execute or resource-intensive functions in your app.
* [**Logs**](https://docs.sentry.io/product/explore/logs.md):
  <!-- -->
  Centralize and analyze your application logs to correlate them with errors and performance issues. Search, filter, and visualize log data to understand what's happening in your applications.

### [Install the Sentry SDK](https://docs.sentry.io/platforms/javascript/guides/gcp-functions.md#install-the-sentry-sdk)

Run the command for your preferred package manager to add the Sentry SDK to your application:

```bash
npm install @sentry/google-cloud-serverless --save
```

```bash
npm install @sentry/google-cloud-serverless @sentry/profiling-node --save
```

## [Step 2: Configure](https://docs.sentry.io/platforms/javascript/guides/gcp-functions.md#step-2-configure)

Make sure to initialize Sentry at the top of your function code and wrap each function with the appropriate helper. Select the tab that matches the kind of function you're using (HTTP, Background, or CloudEvent):

```javascript
const Sentry = require("@sentry/google-cloud-serverless");
// ___PRODUCT_OPTION_START___ profiling
const { nodeProfilingIntegration } = require("@sentry/profiling-node");
// ___PRODUCT_OPTION_END___ profiling

Sentry.init({
  dsn: "___PUBLIC_DSN___",

  // Adds request headers and IP for users, for more info visit:
  // https://docs.sentry.io/platforms/javascript/guides/gcp-functions/configuration/options/#sendDefaultPii
  sendDefaultPii: true,
  // ___PRODUCT_OPTION_START___ profiling

  integrations: [nodeProfilingIntegration()],
  // ___PRODUCT_OPTION_END___ profiling
  // ___PRODUCT_OPTION_START___ performance

  // Add Performance Monitoring by setting tracesSampleRate
  // Set tracesSampleRate to 1.0 to capture 100% of transactions
  // We recommend adjusting this value in production
  // Learn more at
  // https://docs.sentry.io/platforms/javascript/configuration/options/#traces-sample-rate
  tracesSampleRate: 1.0,
  // ___PRODUCT_OPTION_END___ performance
  // ___PRODUCT_OPTION_START___ profiling

  // Enable profiling for a percentage of sessions
  // Learn more at
  // https://docs.sentry.io/platforms/javascript/configuration/options/#profileSessionSampleRate
  profileSessionSampleRate: 1.0,
  // ___PRODUCT_OPTION_END___ profiling
});

exports.helloHttp = Sentry.wrapHttpFunction((req, res) => {
  throw new Error("oh, hello there!");
});
```

## [Step 3: Add Readable Stack Traces With Source Maps (Optional)](https://docs.sentry.io/platforms/javascript/guides/gcp-functions.md#step-3-add-readable-stack-traces-with-source-maps-optional)

The stack traces in your Sentry errors probably won't look like your actual code without unminifying them. To fix this, upload your [source maps](https://docs.sentry.io/platforms/javascript/guides/gcp-functions/sourcemaps.md) to Sentry. The easiest way to do this is by using the Sentry Wizard:

```bash
npx @sentry/wizard@latest -i sourcemaps
```

## [Step 4: Verify Your Setup](https://docs.sentry.io/platforms/javascript/guides/gcp-functions.md#step-4-verify-your-setup)

Let's test your setup and confirm that Sentry is working correctly and sending data to your Sentry project.

### [Issues](https://docs.sentry.io/platforms/javascript/guides/gcp-functions.md#issues)

First, let's verify that Sentry captures errors and creates issues in your Sentry project. Add an intentional error in your function:

```javascript
exports.helloHttp = Sentry.wrapHttpFunction((req, res) => {
  throw new Error("Sentry Test Error - This is intentional!");
});
```

### [Tracing](https://docs.sentry.io/platforms/javascript/guides/gcp-functions.md#tracing)

To test tracing, wrap your code in a span:

```javascript
exports.helloHttp = Sentry.wrapHttpFunction(async (req, res) => {
  await Sentry.startSpan(
    { op: "test", name: "My First Test Transaction" },
    async () => {
      // Simulate some work
      await new Promise((resolve) => setTimeout(resolve, 100));
    },
  );

  res.status(200).send("Success!");
});
```

### [Logs NEW](https://docs.sentry.io/platforms/javascript/guides/gcp-functions.md#logs-)

To verify that Sentry catches your logs, add some log statements to your application:

```javascript
Sentry.logger.info("User example action completed");

Sentry.logger.warn("Slow operation detected", {
  operation: "data_fetch",
  duration: 3500,
});

Sentry.logger.error("Validation failed", {
  field: "email",
  reason: "Invalid email",
});
```

### [View Captured Data in Sentry](https://docs.sentry.io/platforms/javascript/guides/gcp-functions.md#view-captured-data-in-sentry)

Now, head over to your project on [Sentry.io](https://sentry.io/) to view the collected data (it takes a couple of moments for the data to appear).

Need help locating the captured errors in your Sentry project?

* Open the
  <!-- -->
  [**Issues**](https://sentry.io/orgredirect/organizations/:orgslug/issues/)
  <!-- -->
  page and select an error from the issues list to view the full details and context of this error. For more details, see this
  <!-- -->
  [interactive walkthrough](https://docs.sentry.io/product/sentry-basics/integrate-frontend/generate-first-error.md#ui-walkthrough).
* Open the
  <!-- -->
  [**Traces**](https://sentry.io/orgredirect/organizations/:orgslug/explore/traces/)
  <!-- -->
  page and select a trace to reveal more information about each span, its duration, and any errors. For an interactive UI walkthrough, click
  <!-- -->
  [here](https://docs.sentry.io/product/sentry-basics/distributed-tracing/generate-first-error.md#ui-walkthrough).
* Open the
  <!-- -->
  [**Profiles**](https://sentry.io/orgredirect/organizations/:orgslug/profiling/)
  <!-- -->
  page, select a transaction, and then a profile ID to view its flame graph. For more information, click
  <!-- -->
  [here](https://docs.sentry.io/product/explore/profiling/profile-details.md).
* Open the
  <!-- -->
  [**Logs**](https://sentry.io/orgredirect/organizations/:orgslug/explore/logs/)
  <!-- -->
  page and filter by service, environment, or search keywords to view log entries from your application. For an interactive UI walkthrough, click
  <!-- -->
  [here](https://docs.sentry.io/product/explore/logs.md#overview).

## [Next Steps](https://docs.sentry.io/platforms/javascript/guides/gcp-functions.md#next-steps)

At this point, you should have integrated Sentry into your Google Cloud Platform functions, which should already be sending data to your Sentry project.

Now's a good time to customize your setup and look into more advanced topics. Our next recommended steps for you are:

* Explore [practical guides](https://docs.sentry.io/guides.md) on what to monitor, log, track, and investigate after setup
* Continue to [customize your configuration](https://docs.sentry.io/platforms/javascript/guides/gcp-functions/configuration.md)
* Learn how to [manually capture errors](https://docs.sentry.io/platforms/javascript/guides/gcp-functions/usage.md)
* Get familiar with [Sentry's product features](https://docs.sentry.io/product.md) like tracing, insights, and alerts
